Mr. Hewitt, who has had great experience in crossing tame cock-pheasants with fowls belonging to five breeds, gives as the character of all 'extraordinary wildness' (13/42. 'The Poultry Book' by Tegetmeier 1866 pages 165, 167.); but I have myself seen one exception to this rule. Mr. S. J. Salter (13/43. 'Natural History Review' 1863 April page 277.) who raised a large number of hybrids from a bantam-hen by Gallus sonneratii, states that 'all were exceedingly wild.' ..utterly

male hybrids from the pheasant and the fowl act in the same manner, "their delight being to watch when the hens leave their nests, and to take on themselves the office of a sitter." (13/57. 'Cottage Gardener' 1860 page 379.) .. Mr. Hewitt gives it as a general rule with fowls, that crossing the breed increases their size. He makes this remark after stating that hybrids from the pheasant and fowl are considerably larger than either progenitor: so again, hybrids from the male golden pheasant and female common pheasant "are of far larger size than either parent-bird.' (17/39. Ibid 1866 page 167; and 'Poultry Chronicle' volume 3 1855 page 15.)"

cockerels successfully fertilised turkey eggs. Harada & Buss reported hybridisation experiments between Beltsville Small White Turkeys and two strains of chickens. When male chickens inseminated female turkeys, both male and female embryos form, but the males are much less viable and usually die in the early stages of development. When male turkeys inseminated female chickens, no hybrids resulted; however, the unfertilised chicken eggs began to divide. According to Olsen, turkey-chicken crosses produced all males. A supposed turkey × pheasant hybrid was reported by Edwards in 1761.

Duck hybrids

also described duck hybrids in ''The Variation of Animals and Plants Under Domestication'':

Hybrids are often raised between the common and musk duck, and I have been assured by three persons, who have kept these crossed birds, that they were not wild; but Mr. Garnett (13/45. As stated by Mr. Orton in his 'Physiology of Breeding' page 12.) observed that his hybrids were wild, and exhibited 'migratory propensities' of which there is not a vestige in the common or musk duck.
